The roster for the upcoming brawler just got larger by two with the Sony's announcement that "Starhawk" hero Emmet Graves and "Gravity Rush" heroine Kat (pictured) would be joining the lineup as in early 2013. Both will be available for free for the first two weeks of their release, according to a post on the PlayStation blog.

Neither character is apparently for public display as of yet, but the post does describe some of their game-specific moves and specials which will be making their way into "Battle Royale." Emmett will be able to build and deploy weapons and gear in the arena while Kat will be able to jump around and twist her own gravity to get an advantage on opponents.

"PlayStation All-Stars Battle Royale" will be available for the PS3 and PS Vita on November 20th.
